Another Goldilocks Zone?

[VJOFan]

Mouthpiece pressure and hand grip are often discussed as needing to be balanced. Not too much/firm, not too little/lax.

I think corners of the embouchure also have a Goldilocks zone where being too firm can be fatiguing and too loose can affect the sound.

I found relaxing a little vastly improved my Bordogni endurance tonight.
